BACKGROUND OF THE INVENTION

Mobile communications have changed the way people communicate and mobile phones have been transformed from a luxury item to an essential part of every day life. The use of mobile phones is today dictated by social situations, rather than hampered by location or technology. While voice connections fulfill the basic need to communicate, and mobile voice connections continue to filter even further into the fabric of every day life, the mobile Internet is the next step in the mobile communication revolution. The mobile Internet is poised to become a common source of everyday information, and easy, versatile mobile access to this data will be taken for granted.

As the number of electronic devices enabled for wireline and/or mobile communications continues to increase, significant efforts exist with regard to making such devices more power efficient.

In addition, the polarization of the transmitted field and the beam shape may be controlled by activating appropriate switches in the patch antennas 300 and/or 310, as described with respect to FIG. 3B. In an embodiment of the invention, both the frequency and direction of transmission may be configured for communicating signals between chips in the wireless device 150. In this manner, signals may be communicated at very high frequency within the wireless device 150 without drawbacks with wire traces between chips due to stray impedances, for example.
